Heamo (diabetic emergencies & Med overdose) Flashcards
What does insulin do
What is the difference between type 1 and type 2 diabetes
What are our signs for Hyperglycemia
What is the patho behind DKA
Signs and symptoms:
Hyperglycemia
Slow onset
Hypovolemia
Abdo pain
Nausea/vomiting
Kussnaul’s breaths
Ketone breath
What is the path of HHS (HONK)
Signs and symptoms:
Insiduious affects (often mistaken for stroke)
Weakness
Severe dehydration
3 P’s
Neuro signs & symptoms
Hemiperesis, aphasia, visual hallucinations, seizures, coma
When administering fluids with patients with hyperglycemia should we give as a full open running line
No!
This can increase the chances of causing fluid shifts therefore increasing increased ICP
What is poisioning
This is the excessive administration of medication that produced harmful effects
Factors can depend on
Pharmacokinetic factors
Medication itself
Dose
Rate
Route
Or physiological factors
Age/weight
comorbidities
other meds or substances
What are the 3 main ways that poisoning occur from
What are the 2 main classes/types of meds
Opioid meds
Increased binding to opioid receptors.
Excessive GABA and parasympathetic activity and inhibition of excitatory neurotransmitters
Some common sings and symptoms that can arise are
CV depression, bradycardia, hypotension, hypothermia
Resp depression (desensitization to chemo receptors), apnoea, hypoxia, hypercarbia
Neuro-sedation, reduced reflexes, miosis (pupil constriction)
What are the roles of seritonin
These receptors are predominatley found in the CNS and GI tract.
What is seritonin syndrome
Accumulation of serotonin promotes CNS hyperexcitability (increased sympathetic activity)
What is our management for serotonin syndrome
What are tricyclic antidepressent meds
These work by inhibiting the reuptake of noradrenaline and serotonin
What is our managment for TCA poisiong
